Rancilio. It's the most recognized name in commercial-quality espresso machines and grinders. Featuring 55mm burr grinding plates crafted of the finest tempered steel, the Rocky is designed to deliver 55 different types of quality grounds at the press of a button, all without imparting additional heat during the process. Rocky's large, UV-resistant bean hopper holds more than a half a pound of beans so you won't have to stop mid-grind during a large dinner party for a refill. Learn More
